Selena Gomez is taking time off from her "Revival" world tour as she battles anxiety, depression and panic attacks following her Lupus diagnosis, which she made public in 2015.

"As many of you know, around a year ago I revealed that I have lupus, an illness that can affect people in different ways," Gomez told People Magazine. "I've discovered that anxiety, panic attacks and depression can be side effects of lupus, which can present their own challenges."

"I want to be proactive and focus on maintaining my health and happiness and have decided that the best way forward is to take some time off. Thank you to all my fans for your support. You know how special you are to me, but I need to face this head on to ensure I am doing everything possible to be my best."

The singer was scheduled to perform in Canada in September before heading to Finland and Sweden in October, according to her tour schedule. It's unclear if those shows are going to be rescheduled and how much of her tour is going to be impacted. The tour is currently scheduled to run through Dec. 18 and conclude in Guadalajara, Mexico.
